Too Much Fat Causes
posted May 12, 2005
Obese people may be “super-sizing”
more than just their waistline.
A new study shows at least some of that extra fat could be ending up in their
livers as well.
The research is the first to link dietary fat to a condition called nonalcoholic
fatty liver disease, or NALFD. The condition is one of several included in the
metabolic syndrome -- a collection of conditions that put people at higher risk
for heart disease and strokes. Scientists know people with NALFD are not able to
clear fat from their livers, as is normally the case, but they haven’t been sure
whether the fat comes from eating fatty foods or is simply produced by the body.
University of Minnesota investigators made the discovery after tagging food
containing fat with deuterium -- a form of hydrogen they could then use to
identify where the fat ended up in the body. Obese people with NALFD who were
already scheduled to undergo liver biopsies ate the food, then the researchers
examined the biopsies for evidence of the deuterium to determine if the dietary
fat had, indeed, traveled to the liver and gotten stuck there.
Results showed it did. About 20 percent of the fat found in the livers of these
patients came from dietary fat.
“The bottom line is, this is a clear implication that if one eats too much fat,
as in the film ‘Super Size Me,’ fat becomes deposited in the liver,” says lead
study author Elizabeth Parks. “This leads to a kind of liver toxicity that would
be good to avoid.”
